Abstract

A method and a system for detecting a semiconductor device are provided. The method comprises obtaining an image of the semiconductor device, evaluating a feature of the image, detecting a defect of the semiconductor device based on the feature, extracting a defect information for the defect, calculating a defect die ratio (DDR) in response to the defect and analyzing a relation between the DDR and the defect information.
